The GRACO 187545 NUT, JAM, HEX is a low-profile, internally threaded fastener designed to secure components in place within GRACO equipment. Its material is not specified in available sources, but it is intended for use as a locking nut to prevent loosening of assemblies, especially in high-vibration environments.

Key Features:

• Jam Hex Nut
• Hexagonal, low-profile
• Low-profile design for space-constrained applications
• Reliable locking function to prevent loosening
• Essential for maintaining equipment integrity in high-vibration environments

Applications:
Used to secure and lock components in place on GRACO equipment, particularly in applications where vibration or movement could cause standard nuts to loosen.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of equipment. Non-genuine parts may not meet required specifications and could compromise equipment reliability.
• Install the jam nut against the work surface before tightening the main nut to lock it in place
• Ensure threads are clean and undamaged before installation
• Tighten securely but avoid over-torquing to prevent thread damage
• Regularly inspect jam nuts for signs of wear or loosening
• Replace with genuine GRACO parts if damage or excessive wear is detected
